BACKGROUND

On the one hand, the 16th century saw the birth of the luxury watchindustry, with a tradition of making mechanical watches that has beenhanded down for more than 400 years. On the other hand, theminiaturization of electronic circuits and the increase in capacity ofportable power sources have led to the introduction of numerouselectronic devices. In particular, at the end of the 1960s, the firstwatches incorporating a quartz oscillator appeared. A few years later,the analogue display with hands was replaced by a digital display. Sincethen, two main development routes have been followed by designers ofwatches, with some pursuing the production of essentially mechanicalwatches, and others being committed to the production of purelyelectronic watches.

These two routes have developed in parallel, never or almost neveroverlapping.

Mechanical watches, or watches with a mechanical movement, haveundergone a considerable number of developments, in particular in thecreation of new complexities, but these developments are almostexclusively based on purely mechanical techniques, without the use ofany electronic circuit apart from optionally the quartz oscillator andits power supply. In any case, the designers of mechanical watches havesought to retain the maximum amount of mechanical movement for measuringand displaying time, while keeping to an absolute minimum theintroduction of electronic circuits for performing associated functions.For this reason, mechanical watches are often referred to by theexpression “traditionally made watches”.

Furthermore, the cost of mechanical watches has remained relativelyunchanged in comparison with that of electronic watches, which hasfallen sharply. Thus, mechanical watches have gradually come to beregarded as luxury items, with prices ranging from several thousandeuros to several million euros. Production runs of mechanical watchesare limited to approximately three million per annum and globally amountto approximately one hundred million units.

Moreover, electronic watches have developed greatly since theintroduction of the digital display. The watch case has graduallyincorporated new functions, as the calculation capacities of integratedcircuits have increased and their power consumption has reduced. Certainwatches have for example incorporated a calculator function, a satellitepositioning system, or also a player of digital music files. Nowadays,watches incorporate functions that are even more sophisticated, andabove all more numerous, most often being based on a hardware andsoftware architecture identical or similar to that of a mobile device.By mobile device or apparatus, is meant a computer device suitable forbeing carried and used when a user is on the move. In particular, themobile device must comprise autonomous power supply means. It may inparticular be a portable computer, a “personal digital assistant” oralso a “smart phone”. In reality, electronic watches nowadays correspondto mobile devices in the general form of a watch. They are thus called“smart watches”. However, their aesthetic appearance and technicalelegance is radically changed, and the functionalities offered make thetime display of secondary importance.

Unlike mechanical watches, electronic watches, even expensive ones, arenot considered luxury items, but are aimed at customers who areenthusiastic about new information and communication technologies.

Consequently, mechanical watches and electronic watches belong to twofields that are not only different from one another, but also completelyisolated from, or even opposed to one another. If it seems impossible toenvisage a synergy between mechanical watches and electronic watches,the fact remains that each type of watch has limitations as regards theexpectations of some customers. On the one hand, current electronicwatches suffer rejection by the wearers of mechanical watches, thelatter being attached to the craftsmanship and aesthetic value of thesewatches. On the other hand, mechanical watches fulfil none of thefunctions accessible to smart watches. A user cannot therefore haveaccess to the features of both these types of watches simultaneously,except by wearing two different watches. However, it has in practiceproved inconvenient to multiply the elements worn by a person, inparticular on a wrist strap.

SUMMARY

A purpose of the invention is in particular to overcome some or all ofthe aforementioned drawbacks by proposing a new paradigm in the field ofwatches. This paradigm is based on the possibility of incorporating thefunctionalities of a smart watch into a mechanical watch, preferably ina reversible manner. This incorporation consists of providing anelectronic module fulfilling the functionalities of a smart watch, and adisplay screen connected to the electronic module, capable of beingmechanically coupled to a watch of the traditional type. More generally,the invention aims to incorporate functionalities of mobile applicationsinto an item, in particular an item worn or attached around a part of aliving being, generally a human being. By item of value, is meant anypiece of jewelry such as a bracelet, a watch, a chain or a pendant, forexample made of a precious metal, and any electronic device designed tobe worn by a living being. The electronic device can in particular be anelectronic watch or a health bracelet. When the mobile device equips anelectronic watch, it makes it possible to add functionalities to thosealready present in the electronic watch. The health bracelet, alsocalled a fitness bracelet, usually has the general shape of a wristwatchand can comprise various sensors such as a movement sensor, atemperature sensor, and a heart-rate monitor. The item of value can beworn around the waist, wrist, ankle, or neck of the living being.

More precisely, the invention relates to a mobile device capable ofequipping any item, in particular an item of value, worn or attachedaround a part of the body of a living being, preferably a human being,the mobile device comprising:

-   -   an electronic module capable of running a mobile application,    -   a display screen connected to the electronic module and designed        to display information relating to the mobile application, and    -   a fastening support designed to fasten the display screen to an        item in a detachable manner, when said item is worn or attached        around a part of the living being's body.

According to a particular embodiment, the mobile device is capable ofprotecting and equipping, by superimposition, any item worn or attachedaround a part of the body of a human being, such as the waist, wrist,ankle, or neck, the item comprising a first outer surface intended to beeasily visible to the human being when wearing the item, the mobiledevice comprising:

-   -   an electronic module capable of running a mobile application,    -   a display screen connected to the electronic module and designed        to display information relating to the mobile application, and    -   a fastening support, the shapes and dimensions of which are        designed so that the mobile device can successively equip any        item worn by the human being, and in order to be able to fasten        at least the display screen to an item, in a detachable manner        and by superimposition, when said item is attached around a part        of the body of the human being, the mobile device being designed        so that, when the display screen is fastened to the item, it        covers at least a part of the first outer surface of this item.

The electronic module must be capable of running one or more mobileapplications. By mobile application, is meant any computer softwarecontaining a sequence of instructions carried out with a view tofulfilling a given functionality. By way of example, the mobileapplication can consist of a video game, an electronic organizer, or adigital music reader. The mobile device can also provide mobileapplications that are known as thus-named connected applications, i.e.exchanging data with external devices, by wired connection orwirelessly. In particular, the mobile applications can be an e-mailclient, a web browser, or a global navigation satellite systemassistant. The mobile device according to the invention can alsocommunicate with other mobile devices, in particular with a personaldigital assistant or a mobile telephone. The electronic module can thenrun mobile applications managing the sending and receiving of telephonecalls and short messages (SMS) by the mobile telephone, and allowingremote consultation of information contained in an external mobiledevice, such as an electronic organizer or photos. Of course, theseexamples of applications are not limitative and many other applicationscan be envisaged, depending on the resources of the mobile device.

The mobile device according to the invention is provided in order toequip any item, in particular any item of value, worn or attached arounda part of the body of a living being. In the case in point, thefastening support makes it possible to “affix” at least the displayscreen onto the item of value, so that this item of value has a displayscreen providing functionalities identical or similar to those of anymobile device. Preferably, the display screen is secured to the item ofvalue, or a part of the item of value. In particular, when the item ofvalue comprises a screen or a surface displaying information, forexample a watch face, the display screen of the mobile device accordingto the invention is secured to the screen or the information displaysurface. The display screen of the mobile device can also cover anotherpart of the item or the item of value. It can in particular cover awatch strap or gems in a piece of jewelry.

The mobile device can in particular equip any type of watch,irrespective of its mechanism, shape, and means of attachment to a user.In the case in point, the watch can be a wristwatch, a pocket watch, apendant watch, a mechanical watch, a quartz watch, a watch with ananalogue or digital display. The mobile device can moreover equip ahealth bracelet, a piece of jewelry or any electronic device.

The electronic module can comprise a field programmable gate array, orFPGA. It can also comprise a memory capable of storing the mobileapplication and data processed by the mobile application, and aprocessor or a microprocessor capable of running the mobile application.

The display screen is for example a liquid crystal display (LCD) screen,a light-emitting diode (LED) screen or an organic light-emitting diode(OLED) screen. The screen can comprise Gorilla Glass (registered trademark) or Willow Glass (trade mark). Other display technologies can ofcourse be used.

The mobile device preferably comprises an acquisition interface designedto allow the user to enter data that can be used by the mobileapplication. This acquisition interface forms an input peripheral forthe electronic module. It can be one or more switches, for examplepushbuttons, or a keyboard. The acquisition interface can also be formedby providing a touch display screen.

According to a preferred embodiment characteristic, the mobile deviceaccording to the invention is produced so as to minimize the change inappearance of the item of value that it is to equip. The mobile devicecan be designed so as to leave the maximum amount of the item of valuethat it is to equip visible. The different components of the mobiledevice can have reduced dimensions and/or be produced with transparentmaterials. In particular, the fastening support can be made of atransparent material, for example transparent ceramic or transparentplastic, Gorilla (registered trade mark) Glass or Willow (trade mark)Glass. The mobile device can have a shape substantially similar to theshape of the item of value to be equipped with dimensions substantiallygreater than those of the item of value or of the part to be equipped,preferably by superimposition. The mobile device can thus protect theitem of value or a part against the risks of damage, depending on thewhereabouts and change in activity of the wearer. According to aparticular embodiment, the fastening support has shapes and dimensionsdesigned so that the mobile device can successively equip differentitems worn by the human being, and so as to be able to fasten at leastthe display screen to the item considered, in a detachable manner and bysuperimposition. In practice, the fastening support can have dimensionssubstantially greater than those of the items that it is to equip. Itshould be noted that the fastening support can be suitable for equippingitems the dimensions of which differ substantially from one item toanother. In order to do this, the fastening support can have dimensionseach of which is at least equal to the greatest respective dimension ofthe different items to be equipped. The fastening support can, inaddition or instead, have a certain elasticity.

The mobile device can also comprise means for communicating data withother pieces of electronic equipment, in particular other mobile devicessuch as a mobile phone. These means can be wireless communication means.By way of example, the mobile device can comprise a transmitter-receiverbased on Bluetooth technology (IEEE 802.15.1 standard) or Wi-Fi (IEEE802.11 standard). The mobile device according to the invention can thenexchange data with other pieces of electronic equipment, in particularin order to control them and/or to display on the display screen,information contained in and/or processed by these pieces of electronicequipment. In the case in point, the wireless communication means canmake it possible to synchronize data with one or more pieces ofelectronic equipment. The mobile device can also constitute a computerterminal of a computer network, in particular in “cloud computing”.

According to a particular embodiment, the mobile device also comprisesmeans for generating and/or storing secure data. The secure data can bedata relating to the wearer of the item of value, for exampleinformation on their state of health (medical passport), bankingdetails, and/or codes giving access to buildings, hotel rooms, orvehicles. The means for generating and/or storing secure data canconsist of a data encryption algorithm, or a storage memory. The memorycan in particular be designed to prevent the stored data being readwithout the user's authorization. The memory can in particular beinaccessible for reading by a device other than the mobile device. Thestored data can be encrypted.

The mobile device according to the invention is particularly suitablefor an item of value comprising a case, for example a watch or a healthbracelet. The mobile device can then be fastened to the case. By case ismeant any container capable of holding components. The case can havevarious general shapes, in particular cylindrical or parallelepipedal.It comprises a first outer surface intended to be seen easily by theliving being when wearing the item of value. In the case of a watch, thefirst outer surface corresponds to the surface on which the watch faceindicating the time is formed. In the case of a wristwatch, this surfaceis opposite the surface which comes into contact with the user's wrist.The first outer surface, and in particular the watch face, may or maynot be covered by a protective glass. The first outer surface and thewatch face can have a flat or curved surface. The mobile device isadapted to the shape of the case. In particular, it can be designed sothat, when the display screen is fastened to the item of value, itcovers at least a part of the first outer surface of the case.Preferably, the fastening support is designed to be able to fasten thedisplay screen to the case. According to other embodiments, the mobiledevice can be designed to cover other parts of an item of value, inparticular a bracelet.

In order to facilitate the use of the mobile device, the latter can bedesigned so that, when the display screen is fastened to the item ofvalue, it covers at least a part of the first outer surface of the case.It can in particular cover a top or bottom half of this first surface,or the whole of this first surface. The user or the wearer of the itemof value thus intuitively accesses the information relating to themobile application. It should be noted that, in the case of a watch,when the first outer surface of the watch is covered by a protectiveglass, the display screen fits on top of this protective glass.

Still with the aim of limiting the change in appearance of the item ofvalue equipped with the mobile device, the display screen, covering atleast a part of the first outer surface of the case, is designed so asto leave this first outer surface visible in the absence of informationdisplayed on the display screen. In other words, the display screen iscapable of adopting a state in which it appears transparent to the userof the watch. Of course the screen can be partially opaque, inparticular at its edges where the control electronics are arranged.Preferably, over at least 80% of its surface, corresponding to itsdisplay surface, the screen has a transmission coefficient greater thanor equal to 50% (advantageously greater than or equal to 75%) in thewavelength band visible to the living being wearing the item of value(between approximately 380 nm and approximately 780 nm in the case of ahuman being).

According to another feature of the invention, the mobile device canform a device for protecting the item of value that it equips, whileallowing complete or partial transparency over the latter, and thusensuring an attractive aesthetic appearance of the mobile device-item ofvalue assembly. The mobile device can cover all or part of the item ofvalue, in particular all or part of the case of a watch, the latterelement being a single non-replaceable part, as no spare part isavailable from luxury watch manufacturers. It then protects the item ofvalue from impacts and friction against other items. It can also beprovided in order to protect the item of value from ultravioletradiation. The mobile device can also form a compartment that isimpervious to certain fluids, in particular water, and sand.

More particularly, the fastening support can comprise a part, called acover, designed so that, when the display screen is fastened to the itemof value, this part covers at least a part of the first outer surface ofthe case.

The display screen, covering at least a part of the first outer surface,can then form all or part of the cover of the fastening support.

The case of the item of value can comprise a second outer surfaceforming a back of the case. In the case of a wristwatch, the backcorresponds to the surface coming into contact with the user's wrist.

According to a particular embodiment, the fastening support comprisesanother part, called the back support, designed so that when thefastening support is fastened to the item of value, the back supportcovers at least a part of the back of the case. The cover and the backsupport then define between them a protective compartment capable ofreceiving the case. This compartment can envelop the whole case, or onlya part thereof. Thus, the fastening support has a shape substantiallysimilar or complementary to the shape of the case or a part thereof tobe protected, and dimensions substantially greater than those of thecase or of the part to be protected.

The fastening support can also comprise a side flank mechanicallylinking the cover and the back support, so as to form a U. The coverforms a first arm of the U, the back a second arm of the U, and the sideflank a part linking the two arms of the U. The mobile device can thusbe coupled to the case by sliding, while the item of value is in placeon the user. Advantageously, the back of the fastening support has arelatively small thickness, for example less than or equal to 2 mm, inorder to be able to be introduced between the back of the watch case andthe user's wrist without having to loosen the watch strap.

With the aim of reinforcing the protection of the watch, the fasteningsupport can also comprise a closing side cover capable of adopting afirst thus-named open position, in which the fastening support can beput in place on the case by sliding, and a second thus-named closedposition, in which the closing side cover closes an open portion of theU. In other words, in the closed position, the fastening support forms aclosed O-shaped contour.

In another version of the device according to the invention, the covercan be mounted on the back support by means of a hinge, a “T”-, “U”-, or“L”-shaped slide or any other suitable means. Similarly, the side covercan be mounted on the cover by means of a hinge, a “T”-, “U”-, or“L”-shaped slide or any other suitable means.

The mobile device can comprise autonomous power supply means, i.e.independent of the item of value equipped with the mobile device. Thepower supply means can be incorporated into the same casing as theelectronic module and the other components of the mobile device, or allor part of it can be located separately. By way of example, the powersupply means can be designed to be fastened to the wrist strap of theitem of value. The power supply means can comprise a cell or a battery.They can also comprise a solar energy collector or an infrared wavecollector. The power supply means can also comprise means for generatingelectrical power by movement, by induction charging means, by ambientbackscatter, or by means for recovering the electrical and/or mechanicalenergy from the mechanism of the watch equipped with the mobile device.Ambient backscatter is a new technology which makes it possible to usethe energy contained in the surrounding waves present around an item inorder to generate energy for applications that consume it.

According to a first embodiment variant of the invention, the electronicmodule is not incorporated into the case of the item of value, forexample into the watch case. It can in particular be incorporated intothe back support of the fastening support. In this case it is notvisible to the user when the mobile device is in place on the item ofvalue. The electronic module could also be located separately on anotherpart of the item of value, for example on the wrist strap. Similarly,other components of the mobile device can be incorporated into the backsupport or into the cover of the fastening support.

According to a second embodiment variant of the invention, theelectronic module is designed to be incorporated into the case of theitem of value. In this case, the case is designed to receive theelectronic module. In the case in point, it comprises a housing formedin the case in order to receive the electronic module. Preferably, thishousing is easily accessible in order to allow easy insertion andremoval of the electronic module. The electronic module can then beeasily replaced, for example with a more recent version.

According to this second embodiment variant of the invention and in aparticular embodiment, the display screen can be merged with theprotective glass which is fastened to the watch case.

According to a particular embodiment, the fastening support is designedto receive a wrist strap making it possible to attach the mobile deviceto the wrist without having to wear a watch. The wrist strap can inparticular be attached to the back support of the fastening support.This particular embodiment makes it possible to arrange the autonomouspower supply means in the position of the location originally reservedfor the watch case.

It should be noted that the mobile device according to the invention,although it is affixed onto an existing item, has all the features foroperating autonomously, independently of this item. In the case inpoint, it comprises the means making it possible to provide a mobileapplication to a user (electronic module, display screen), without usingthis item's hardware and/or software resources. Moreover, the mobiledevice is designed to be affixed onto different, already existingobjects, onto products that are available on the market or not, withoutthese items having been designed to receive the mobile device. Inparticular, the shapes and the dimensions of the fastening support canbe designed in order to allow fastening to an existing item. Thus, themobile device does not constitute a module dedicated to a certain item,but a generic device that can be affixed onto items the shapes anddimensions of which differ or, more generally, an incrementation ofstandardized generic devices that can be affixed onto a range of itemsof varying forms and dimensions.

The mobile device can be associated with an interactive platform. Theinteractive platform, having the general shape of a plate, is capable ofbeing fastened to the mobile device in a detachable manner. It comprisesfor example means for elastic coupling to the back support of thefastening support. The interactive platform can comprise anycommunication and information means. By way of example, it can comprisea SIM card or a recess for a SIM card, a near field communication (NFC)tag, a radio-frequency identification (RFID) tag, a one- ortwo-dimensional barcode (flashcode or QR code). These communication andinformation means can in particular be used as confidential datacarriers, or as keys giving access to systems or secure premises.

A subject of the invention is also an assembly comprising a watch and amobile device as described previously. The watch can comprise a case inwhich a housing capable of receiving the electronic module is formed.

A subject of the invention is also an assembly comprising a mobiledevice and an interactive platform as described previously.

By way of example, thebody can comprise one or more grooves, for example U-, L- or T-shaped,and the cover can comprise a male piece with a shape complementary tothe groove, so as to allow sliding of the cover relative to the body.The male piece can be integral with the cover. It can also correspond tothe peripheral edge of the cover.

The case can also comprise sealing means ensuring sealing between thecompartment and the external environment in the closed position. Thus,the items held in the case are protected against any ingress by externalelements such as sand, water and dust. The sealing means can inparticular comprise a seal arranged between the body and the cover, thecase being arranged so that the seal is compressed in the closedposition of the case.

In order to secure the case in the closed position, the interactiveprotective casing can comprise locking means suitable for keeping thecase in the closed position. In particular, the locking means cancomprise a screw-nut assembly arranged so as to secure the body to thecover in the closed position. In a first embodiment example, the lockingmeans can comprise a threaded element provided in order to pass throughthe cover and be screwed into a threaded opening arranged on the body,so that the screwing down of the threaded element tightens the coveragainst the body of the case. In a second embodiment example, thelocking means can comprise a threaded element and a nut. The threadedelement is provided in order to pass through both the cover and thebody, and cooperate with the nut so that the screwing of the threadedelement into the nut tightens the cover against the body of the case.These locking means ensure closing of the lock; they can comprise afingerprint key, a mechanical or electronic key.

With the aim of allowing the secure transport of the interactiveprotective casing according to the invention, the case advantageouslycomprises external attachment means. These external attachment meansmake it possible to attach the protective casing to a part of the livingbeing's body. They can in particular comprise one or more shapesprovided to be fastened onto a belt or to receive a belt, a chain, orany means producing a loop around a part of a person's body, such as thewaist, arm, neck or leg. For example, the external attachment means cancomprise loops for receiving a belt.

With the aim of allowing secure storage of the case, the case can alsocomprise securing means. These securing means are provided for attachingthe case to a secure docking station, the docking station being able inparticular to be fastened to a wall, or to an internal wall of a safe ora vehicle.

The signalling can beaccompanied by data relating to the position of the protective casingdetermined by the satellite positioning system receiver.

The interactive protective casing thus allows several types of usedepending on the requirements of the user and the desired level ofprotection:

-   -   A first level of protection is provided by the processing means        and the means for wireless communication with the pieces of        electronic equipment worn by the user of the protective casing.    -   A second level of protection is provided by the compartment of        the case enclosing the item of values, the protective casing        being held in the hand or around the waist of the user.    -   A third level of protection is provided by arranging a chain        linking the protective casing to the wrist or to the waist of        the user.    -   A fourth level of protection is provided by fastening the        interactive protective casing to a secure docking station.        Docking stations can be installed at different sites.    -   A fifth level of protection is provided by an anti-intrusion        sensor and a satellite positioning system.

A subject of the invention is also a docking station for the interactiveprotective casing described above. In particular, the docking stationcomprises:

-   -   an engaging shape cooperating with the securing shape of the        case in order to position the interactive protective casing on        the docking station in a thus-named assembled position, and    -   immobilizing means designed to immobilize the interactive        protective casing on the docking station in the assembled        position.

The engaging shape is presented for example in the form of one or moretabs designed to be inserted into the securing shape of the case of theprotective casing, for example into its loops. The engaging shape andthe securing shape then form a slide link between the interactiveprotective casing and the docking station.

The immobilizing means are designed to immobilize the interactiveprotective casing on the docking station. In other words, they aredesigned to eliminate any residual degree of freedom between theprotective casing and the docking station. In the case of a slide link,the immobilizing means eliminate the degree of freedom in translationalong the axis of the slide link. In an embodiment example, theimmobilizing means comprise a stop part and a fastening element. Thefastening element is designed to secure the stop part to the engagingshape in a detachable manner. The fastening element can comprise asecurity screw, i.e. a screw the imprint of which formed on its head hasan unconventional shape. The stop part can in particular comprise asupport surface coming into contact with a surface of the case in orderto prevent movement of the case with respect to the docking station.These immobilizing means ensure closing by means of locking.

More generally, the immobilizing means can be of the same type as thelocking means of the interactive protective casing. They can comprise afingerprint key, a mechanical or electronic key.

DETAILED DESCRIPTION

As the embodiments described below are in no way limitative, it ispossible in particular to consider variants of the invention comprisingonly a selection of characteristics described below, in isolation fromthe other characteristics described (even if this selection is isolatedwithin a sentence containing these other characteristics), if thisselection of characteristics is sufficient to confer a technicaladvantage or to differentiate the invention with respect to the priorart. This selection comprises at least one, preferably functional,characteristic without structural details, or with only a part of thestructural details if this part alone is sufficient to provide atechnical advantage or to distinguish the invention from the prior art.

In the remainder of the description, the mobile device according to theinvention is considered as being suitable for equipping a watch, andmore particularly a case of a wristwatch. However, the mobile device canequip any type of case, for example the case of a health bracelet, asmart watch or a chronometer. More generally, it can equip any item, inparticular any item of value, in an autonomous and generic manner. Thefastening supports hereafter described in the figures make it possibleto successively affix at least the display screen of the generic mobiledevice onto different items worn by the human being.

FIGS. 1 to 4 show, in four different views, a first example of a mobiledevice according to the invention. FIG. 1 shows, in a three-quarterview, the mobile device in a thus-named closed position. FIGS. 2 and 3show, in a side view and a three-quarter view, the mobile device in athus-named open position. FIG. 4A shows, in a three-quarter view from afirst viewpoint, a closing side cover of the mobile device. FIG. 4Bshows, in a three-quarter view from a second viewpoint, a part of afastening support of the mobile device. The mobile device 1 comprises afastening support 2, a display screen 3, an electronic module 4, shownin FIG. 2, and power supply means 5, shown in FIGS. 3 and 4B. Thefastening support 2 comprises a first part forming a cover 21, a secondpart forming a back 22, and a third part, called a side flank 23 linkingthe cover 21 to the back 22, so as to form a U-shaped profile. Thisprofile is capable of surrounding a case of a watch, as explained below.The fastening support 2 can moreover cover all or part of the horns ofthe watch case. Preferably, the cover 21, the back 22 and the side flank23 are formed in a single piece, for example by moulding orthree-dimensional printing. The fastening support 2 can also comprise aclosing side cover 24 capable of adopting a closed position, as shown inFIG. 1, and an open position, as shown in FIGS. 2 and 3. In the closedposition, the fastening support 2 has an O-shaped profile. The change inposition is achieved by providing a hinge mechanism. The closing sidecover 24 comprises two tabs 241, 242 having first recesses 243, 244extending along an axis of rotation, and the cover 21 comprises secondrecesses 211, 212. Pins are accommodated in the recesses 243 and 211 onthe one hand, and 244 and 212 on the other hand, so as to form a pivotlink. Of course, any other mechanism can be provided in order to makethe closing side cover 24 move from the open position to the closedposition. The hinge mechanism can be arranged so as to prevent a changein the position of the closing side cover 24 under the effect of gravityor friction against an item. In the case in point, the material of thetabs 241, 242, and that of the cover 21 can be chosen depending on theircoefficient of friction. The tabs 241, 242 and the pins can also beadjusted while gripped in the recesses 211, 212, and 243, 244.

According to a particular embodiment, the fastening support 2 alsocomprises means for locking the position of the closing side cover 24.These locking means can prevent any accidental opening of the closingside cover 24. They consist for example of a mechanism capable of beingreleased by deformation or displacement of an engaging component, suchas elastic rings. They can also consist of lugs, screws, nuts, grooves,retainers, or any other suitable means. In the embodiment example ofFIGS. 1 to 4, the locking means comprise studs 221 formed on the back22, and third recesses 245 formed on the closing side cover 24. Thestuds 221 each cooperate with a recess 245 in the closed position inorder to maintain this position.

The fastening support 2 can comprise, as shown in FIGS. 3 and 4,through-holes 231, 232 formed on the side flank 23 for a chain to passthrough. The chain can ensure an additional means of attachment of themobile device to the wrist of the wearer of the watch. It then forms ameans for securing the watch and the mobile device. The chain can alsoallow a user to wear the mobile device around their neck. Of course, themobile device could comprise any other means of attachment in additionto the fastening support 2, such as for example an autonomous wriststrap.

In the case where the mobile device equips a wristwatch, the back 22 ofthe fastening support 2 is designed to be able to be accommodatedbetween the back of the watch case and a wrist of the wearer of thewatch. The back 22 can have a relatively small thickness, for exampleless than or equal to 2 millimetres (mm). The fastening support 2 canthen be made to fit around the watch case while the latter is already inplace on the user's wrist.

With the aim of further reducing the thickness of the back 22, thelatter can comprise a recess 223, open or not, into which a part of theback of the watch case is inserted.

The fastening support 2 is preferably formed by a transparent material,for example transparent plastic, silicone, Gorilla Glass (registeredtrade mark), or transparent ceramic. Other materials, transparent ornot, can also be used. If not all of the fastening support 2 is made ofa transparent material, it is preferable to produce at least the cover21 from a transparent material, unless it is desired to completely hidethe item of value from prying eyes.

The fastening support 2 forms a device for protecting the watch to whichit is fastened. In fact, its O-shape forms a closed contour and definesa protective compartment for the watch. Possible impacts and scratchesare no longer directly applied to the watch case, but to the mobiledevice.

The display screen 3 is for example incorporated into the cover 21. Thecover 21 can comprise a through-hole dimensioned in order to receive thedisplay screen 3, so that it forms a part of the cover 21. The displayscreen 3 can also be arranged on the cover 21, in a bore or extrathickness of the cover 21.

The display screen 3 is advantageously designed to leave visible thesurface that it covers, in particular, the first outer surface of thecase containing the watch face, in the absence of information displayedon the display screen 3. The display screen 3 has a transmissioncoefficient greater than or equal to 50%, preferably greater than orequal to 75% in the visible wavelength band. On its periphery, thedisplay screen 3 can have a transmission coefficient of less than 50%,for example due to the presence of its control electronics. However, thecontrol electronics cover a surface area less than 20% of the totalsurface of the display screen 3. When the mobile device is not in use,the user can therefore view the watch case without being inconvenienced.With the aim of facilitating the reading of the information displayed onthe display screen 3, the latter can also be designed so that, when itdisplays one or more items of information, the watch case is not visiblethrough the display screen. Such a display mode can in particular beachieved by displaying an opaque screen background.

According to a particular embodiment, the display screen 3 is a touchscreen. In other words, it comprises means arranged on the displayscreen forming an acquisition interface for the user. Any type of touchscreen technology can be used, in particular resistive touch screens andcapacitive touch screens. The display screen 3 can comprise a mechanismfor unlocking the acquisition interface in order to avoid anyunintentional input. The unlocking mechanism can for example bepresented in the form of a cursor to be slid between two predeterminedpoints on the display screen, or along a predetermined path.

The electronic module 4 can be incorporated into the back 22 of thefastening support 2. It can also be arranged other than on the fasteningsupport 2. By way of example, it can be fastened to the strap of thewatch equipped with the mobile device.

The electronic module 4 must be capable of running one or more mobileapplications. By mobile application, is meant any computer softwarecontaining a sequence of instructions carried out in order to perform agiven functionality. By way of example, the mobile application canconsist of a video game, an electronic organizer, or a digital musicreader. Of course, these examples of applications are not limitative andmany other applications can be envisaged, depending on the resources ofthe mobile device.

The electronic module 4 comprises for example a field programmable gatearray (FPGA). It can also comprise a software or partially softwarearchitecture. The electronic module 4 can then consist of a processor ora microprocessor associated with a memory, for example a flash memory.The memory contains the mobile application(s), and the microprocessorruns them.

FIG. 5 shows the mobile device 1 described with reference to FIGS. 1 to4 equipping a wristwatch. The wristwatch 50 comprises a case 51, and awatch strap 52. The case 51 has a general cylindrical shape. Itcomprises an outer surface forming a watch face, a protective glass 511covering the watch face, and horns of the case 512, to which the watchstrap 52 is fastened.

FIG. 6 shows an interactive platform capable of equipping the mobiledevice 1 described with reference to FIGS. 1 to 5. The interactiveplatform 60 for example has the general shape of a plate 600. The plateis preferably sufficiently thin, for example of the order of onemillimetre, for it to be positioned between the back 22 of the support 2and the wrist of a user. The interactive platform 60 comprises twoperipheral engaging rims 61 capable of being coupled by elasticdeformation to the back support 22 of the support 2. Any other linkingmeans could be provided on the mobile device 1 and/or the interactiveplatform 60 to make it possible to fasten the interactive platform 60 tothe support 2 in a detachable manner. It could in particular be a grooveformed in the support 2, in which the interactive platform 60 couldslide. In the example of FIG. 6, the interactive platform 60 comprises arecess 62 for a SIM card 63, a near-field communication (NFC) tag 64,and a two-dimensional barcode 65 fastened or printed on the plate 600(for example a flash code or a QR code). The interactive platform 60could comprise other communication and information means, such as forexample a radiofrequency identification tag, better known as an RFIDchip or any contactless smart card. Due to its location, the interactiveplatform 60, which is interchangeable, forms a relatively secure datacarrier. In particular, when the mobile device equips a wristwatch wornby a user, the interactive platform 60 is not visible. It thus makes itpossible to store the user's secure data, for example information ontheir health (medical passport or monitoring of their state of health),banking information and/or electronic keys giving access to buildings,hotel rooms, or vehicles.

FIG. 7 shows a second example of a mobile device according to theinvention. The mobile device 70 of FIG. 7 essentially differs from themobile device 1 of FIGS. 1 to 5 in that the fastening support 72comprises a cover 721, preferably transparent and comprising the displayscreen 3, and a peripheral rim 722 around the entire perimeter of thecover 721. The peripheral rim 722 is designed to cover the lateralperimeter of a watch case. It can comprise cut-outs 7221 to allow thehorns of the watch case to pass through. The peripheral rim 722 can bemade of a material having elastic properties, so that the fasteningsupport 72 is coupled to the watch case by elastic deformation. Theperipheral rim 722 can in particular comprise lugs 7222, for example atthe cut-outs 7221, suitable for being supported on the back of the case,in the case in point under the horns of the case.

In the embodiment example of FIG. 7, the electronic module 4 can beincorporated in the peripheral rim 722.
